If I were free to get whomever I want, I’d get a plus bassist who can also produce in the studio - like a lot of bassists can. Bassists that can write music, compose, etc.
To apply the analogy, the carpenter who also has an eye for architecture, and knows a thing or two about electrical and plumbing.
So, for example Carol Kaye vs. Brian Wilson: Brian was a serviceable bassist, but was so much more. Come to think of it Carol was more than bass chops as too. Another random example: John Wetton, a good bassist, but much more (song writing, vocalist, serviceable guitarist, and could handle an acoustic bass quite nicely).
If I were 34 (instead of 54), and looking to join a band, I’d love to play bass…but I’d also want to sing and write and maybe produce.
